Types of Propositions

Propositions are broadly divided into two types; namely, affirmation and denial. An affirmation is a positive assertion of something about something. Similarly, a denial is a negative assertion of something about something. Here, we must note that what Aristotle means by ‘something about something’ is what we call the ‘subject’ and ‘predicate’ of a proposition. Aristotle further distinguishes between ‘universal’ and ‘individual’ propositions. By the term ‘universal’ what he means is that which is of such a nature as to be predicated of many subjects, by ‘individual’ that which is not thus predicated[1].
